Well, this is an interesting find considering we are just starting in 2012!
Scientists from the Oxford & Southampton Universities and the National Oceanography Centre (with British Antarctic Survey) have discovered a "lost world" under Antarctica.
This lost world is supposedly teeming with hitherto unknown species.
“For the first time researchers, using a Remotely Operated Vehicle (ROV), have been able to explore the East Scotia Ridge deep beneath the Southern Ocean where hydrothermal vents, including ‘black smokers’ reaching temperatures of up to 382 degrees Celsius, create a unique environment lacking sunlight but rich in certain chemicals.”
